SPECIFICATION forming part of Letters Patent No. 493,050, dated March 7,1893.

Application iiled J' une 1, 1892. Serial No. 435,136. (No model.)

To all whom it may concern.-

Beit known that I, ALEXANDER C. WRIGHT, of the city of Baltimore andState of Maryland, have invented certain Improvements in Brushes, ofwhich the following is a specitlcation.

The object of this invention is t0 produce what is known to the trade asa solid or full center paint brush,as will hereinafter fully appear.

In the description of the said invent-ion which follows, reference ismade to the accompanying drawings forming a part hereof and in which,

Figure l is an exterior View of the improved brush. Fig. 2 is anenlarged central section of the brush illustrating the method 0f driving the handle to its place within the head block, and also the mannerof attaching the central tuft of the brush tothe handle. Fig. 3 is asection similar to Fig. 2, except that a modified construction of thehandle is shown.

Referring to Figs. 1 and 2 of the drawings, Ais the head block to whichthe bodybristles B are attached in the usual manner.

C is the ferrule applied to the outside of the head block and the bodybristles.

D is the handle tapered as usual, the lower or larger end of whichisprovided with a cylindrical cavity a into which the center tuft E isinserted and fastened. Before however the tuft E is inserted in thecylindrical cavity of the handle, the bristles which form the tuft areinclosed in a cylindrical thimble h of some soft metal such as 1ead,andsecured by means of a tapering plug c. The handle has the usual taperingcontour, and the head block a tapering central hole d into which thetapering part of the handle is adapted to Iit tightly.

After the body brush is completed, the thimble with its containedbristlesis entered in the cylindrical cavity d and the whole inserted inthe central hole d of the head block from the under side. Before howeverthis i3 done the bristles of the central tuft are temporarily tied asshown,and over them is placed a tool F the upper end of which comes incontact with the face of the thimble b. The tool is then driven whichhas the effect of forcing the thimble in the central cavity of thehandle and upsetting or expanding it therein, whereby a tight iitiseffected. In this driving operation the handle is also forced to itsplace within the head block. The tool F is then withdrawn and thebristles of the tuft untied.

A brush constructed as described has howeveronedefect,viz: thatthehandlemay shrink in the head block, and become loose so that it will fall out,and if such displacement of the handletakes place, the bristles of thebody also fall out. This defect is entirely obviated in Fig. 3 in whichthe cavityais formed by placing on the handle an iron ferrule G whichprojects over the end of the handle D. In order that the ferrule G maynot become loose on the handle, the upper part'thereof is threaded andscrewed onto the wood. The thread e1nployed to effect this attachment iscoarse as shown in the drawings. It will be seen that in both cases thehandle has a cylindrical cavity into which the thimble of -the centertuft is forced and expanded or upset as described, and the onlydifference between the two constructions, is that in the preferred one,the soft metal thimble is expanded against a metallic wall and thesurface of the handle in contact with the head block is a metallic one.

I claim as my inventionl. In a paint brush of Athe description setforth, the handle provided with a cylindrical cavity and the center tuftwith a soft metal thimble which is inserted in the said cavity andexpanded or upset therein, substantially as specified.

2. In a paint brush of the description set forth, the handle providedwith a metal ferrule which projects beyond the end of the wood therebyforming a cylindricalcavity,and the center tuft with a soft metalthimble which is inserted and expanded in the said cavity, substantiallyas specified.

3. In a paint brush of the description set forth, the wood handle havingan internally threaded ferrule screwed thereon which projects beyond theend of the wood, whereby a cylindrical cavityis produced,and the centertuft with a soft metal thimble which is driven into the said cavity andexpanded therein, substantially as speciiied.
